Accelerometer Method Of Riding-Quality Testing, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

At a meeting of Highway Research Board Committee D-B4 last January, R. L. Rizenbergs presented an oral description of our development of the accelerometer method of measuring road roughness; and representatives from several state highway departments expressed an interest in duplicating our instrumentation. It became incumbent upon us then to prepare a more formal description for distribution to the Committee and other interested parties. The report submitted herewith is intended to fulfill that purpose. No specific action is requested. Copies are furnished for information only.

Construction And Interim Performance Of Silica Sand-Asphalt Surfacing, Robert L. Florence

Kentucky Transportation Center Research Report

The report submitted herewith emanates from continuing efforts to develop sand-asphalt surfacing to a high degree of perfection and as a possible alternative to Class I, Type A, bituminous concrete surfaces. This type of surface excels in skid-resistance and may evolve as a preferred method of surface renewal and de-slicking for worn pavements which are otherwise structurally substantial. This report is concerned principally with observations afforded by the aforenamed, State construction project; it is, in that sense, an interim report.

Experimental Concrete Pavement Containing Fly Ash Admixtures [1965], Ronald D. Hughes

Kentucky Transportation Center Research Report

A 2.388-mi section of four-lane highway in Louisville, Ky., was selected for an experimental fly ash concrete pavement installation. The project was divided into three sections: a control section and two experimental sections containing 94 and 140 lb of fly ash per cubic yard, respectively. The solid-volume of fly ash in excess of that required to replace one sack of cement was considered as fine aggregate. The water was adjusted to provide a slump of approximately 2½ in., and an air-entraining admixture was proportioned at the mixer to provide an air content of approximately 4.5 percent.

Beams and cylinders were …

Experimental Feature, Construction Project F 160(10), U.S. 127, Mercer County, Experimental Guardrail Installations And Performance Studies, James H. Havens

Kentucky Transportation Center Research Report

The report submitted herewith pertains to an experimental installation of aluminum guardrails which was completed in February, 1963. Progress reports, as required by PPM's 60-2 and 50-1.1, have been pending since the project began; however, all of the eligible information has been combined into the current report. Of course, long-time performance histories cannot yet be documented; and, for that reason, the report is considered to be interim rather than final.

Use Of Kentucky Rock Asphalt For De-Slicking Purposes, James H. Havens

Kentucky Transportation Center Research Report

According to Joe Creason's report appearing in the Courier-Journal June 23, 1957 (copy attached), the Kentucky Rock Asphalt Company elected, June 14, 1957, to liquidate. Among the assets was a stockpile of material which was valued at $197,000 (I recall that the stated price, F.O.B. Sweden, in 1955 was $7.00 per ton); this calculates to be 28,140 tons-- which is a small quantity in comparison to the gross production (200,000 to 275,000 tons; $1.2 to $1.75 million) during some prior years. Apparently 1956 was the last year of sales, and I believe that Kentucky was the sole purchaser. Perhaps as …

Construction Of A Class I, Type A Surface Containing Paradise Slag Aggregate (Experimental) Drakesboro-Paradise Road (Ky 176), Robert L. Florence

Kentucky Transportation Center Research Report

The Drakesboro-Paradise Road (KY 176), extending 2.84 miles from its junction with KY 70 at Drakesboro to a point on KY 176 approximately 1.8 miles southwest of Paradise, was surfaced in early August with a 1 1/4-in, course of Class I, Type A bituminous concrete containing 40 percent wet-bottom-boiler slag from the T.V.A. power plant at Paradise, Kentucky. The use of the slag was on an experimental basis, and the objective was to determine the feasibility of utilizing the slag as an anti-skid aggregate in other, high-type,bituminous surfacing in that area. A laboratory investigation preceded the field experiment, and the …

Manufactured (Crushed), Limestone, Fine Aggregate For Portland Cement Concrete, James H. Havens

Kentucky Transportation Center Research Report

Manufactured (crushed), limestone, fine aggregate for use in structural concrete, concrete base courses for pavements, or as may otherwise be designated, shall be manufactured by crushing and sizing aggregate-quality limestones and dolomites. Manufactured (crushed), limestone, fine aggregate shall not be used in concrete surface courses for pavements or bridge decks unless specifically authorized by the Engineer.

Use Of Preformed, Compressed, Neoprene Seals In Joints Of Concrete Bridge Decks, Ronald D. Hughes

Kentucky Transportation Center Research Report

Two types of seals are proposed for installation in contraction and construction joints in Ramp A, Ramp B, and the Main-Line structures from Third Street to Preston Street on Project I64-2(24)4, Jefferson County. The majority of contraction and construction joints are to be sealed with the preformed, compressed, neoprene seals. Specific joints in each structure will be sealed with cold-applied, elastomeric-type, joint-sealing compound; and these will be used as control joints for evaluation of the preformed, compressed, neoprene seals. Installation of all seals will be observed, and inspections will be made periodically. The performance of mastic-type sealants in joints in …

Kentucky Rock Asphalt, Traffic-Bound Bases, George R. Laughlin

Kentucky Transportation Center Research Report

Kentucky rock asphalt (a medium-grained quartz sandstone impregnated with natural bitumen) occurs as major deposits in Edmonson, Grayson, Hardin, Breckinridge, Logan and Warren Counties. Physiographically these deposits occur along the southeastern margin of the Western Coal Field. Geologically the Caseyville formation (particularly the Bee Spring member) of the Pottsville series of the Pennsylvania strata and the Hardinsburg and Cypress sandstones of the Middle Chester series of the Mississippian strata are of interest. The areal geology of Kentucky is shown in Figure 1 and the locations of rock asphalt deposits are depicted in Figure 2.

Performance Of Initial Treatments, Constructed During 1963, James H. Havens, Robert L. Florence

Kentucky Transportation Center Research Report

Seventeen initial bituminous treatment projects were advertised for bids during 1963, which permitted bituminous concrete Class I Surface (hot-mix) as an alternate to Class C-1 Surface (road-mix). The hot-mix surface course was to contain a minimum of 6 percent PAC-9. Eleven of the contracts, totaling 38.841 miles in length, were awarded as hot-mix; and the remaining six contracts, totaling 18.12 miles in length, were awarded as road-mix.

Final Construction And Interim Performance Report: Experimental Use Of Thermoplastic Pavement-Striping Materials, James H. Havens, John W. Scott

Kentucky Transportation Center Research Report

The purposes and objectives of this study are: 1) to evaluate the application and performance characteristics of hot-melt plastic, pavement-striping materials which are presently prominent and known commercially as "Catatherm" and "Perma-Line"; 2) to compare the performance of these materials with the performance of painted stripes applied and re-newed according to the current practices of the Kentucky Department of Highways; and 3) to evaluate the economics of these striping materials in terms of cost-per-pile per-day-of-useful-life. The project is described more fully in the "Proposal..." (approved by Division Engineer, September 7, 1962) and in Report No. 1 (Pre-Construction Report) submitted September …

Weighing Vehicles In Motion [1964], College Of Engineering, University Of Kentucky

Kentucky Transportation Center Research Report

This report describes the construction, installation, testing and performance analysis of three types of dynamic electronic scales; the Taller-Cooper, a commercially developed four load cell scale, the Broke Bridge, an adaptation of a German prototype employing two load cells and the Bean Type Scale, an experimental prototype that uses a pair of instrumented aluminum beams as the weight sensors.
